I've gone through the FX7500 Embedded SDK Programmers Guide ver.0.3 document and ensured my project settings march (except names of classes/package) and I'm sort of out of ideas.

If i remote debug it on the unit, the app runs perfectly and i can see the output i expect (app sends some data to my PC over TCP) but when i build the package using the userAppPackageBuilder and install the DEB package on the unit the app starts and then stops moments later.
